To all fi/.fL--m it may cof/warn Be it known that we. FRANK R. Pnnnr and ERNEST. S.' RIcnAn'nsoN, citizens of the United States, residing nt reston and Anderson. in the counties of Levvis and Modi son :ind Stat-es fest-'Virginia and Indinnzi, respectively', 'have invented certain new und useful Improvements in Gloss#V lForming.; Machines, of Awhich the foll'o'vving is u specification, reference being hud to the accompanying drawings.

Our invention rela-tes n'1ncl`1ines.':md particularly to n'mchines for making bottles or like containers from glass. The primary object of our invention is to provide o machine including two sets of molds wherein the molten glass ugly be plz-iced, und means operating in conjunction with the one set of molds forinitiully part-lj? forming; the vessel. and mechanism operating in conjunction with the second set of molds for completing the formation of the vessel by forcing nir into the interior of the part-ly ormedunolten glass.

A further object o our invention is to provide means operating in conjunction with the first set of molds whereby the nnss of n'ioiten glass placed Within the molds may 'he cnt ott clean across thetop of the mold und then the mold moved into position lienenth n plunger which operates to. force the glass in the mold into contact with the sides of the niold and to forni the initial depres sion or hollow in the molten glass.

A further object of 'the ,invention is the provision in connection with the` .cond set' ot molds of n ph'inger opernjting to close the mold und n vulve nntgnnnticnlly operating when the mold is closed to establish communication between u source oi nir :ind the interior of the mold and specifically vvith the depression previously formed in thc-'molten glass. Y A

Al further object of the invention to provide n'ieains 'for suplmrting thevniolds for movement in n close path1 und means operating' aiutonmiirnllv to shift this mold supporting means step by step in this ch ed path, :intl further in this connection to pao vide means for operating the plunger couctingn'ith the pn: iculnr set oi' molds, seid operation lnliingxpincc when :i mold in registration with the plunger.

Other objc-cts 'will zipper-.r in the course of the following description.

to glass forming My invention is illustrated in the accom- )nnying drawingsF Wherein- Figure 1 is a perspective view of a glass forming machine made in accordance with our invention; Fig. 2 is a longitudinal ver' tical section of the machine; Fig. 3 isjit transverse section on the line 3-3 of Fig. 2; Fig. l is :i top plan view of the tnble, the rotary lnoid carriers mounted thereon, the actuating shafts for the plunger being shown in section; l? 5 is an underside plan 'ien' of the machine; Fig. G is'a trice view of the cmu for operating the gloss blowing plunger; Fig. T is an underside face vien' of the rotatable table, used in conjunction nl'ith the niolds for completing the formation of the. vessel; Fig. S is an elevation, partly in section, of the cam 5G for securing the re-A turn or' the pm vl 1S to its original positim'i;

Fig. 9 is n trngn'ientary sectional view of the tubular plunger 63 showing thevnlve therein; Fig. l0 'isa` detail sectionaiivie'w showingr the lower endof the plunger and the mold cup 27 thereon with l the operating springs.

Referring to` these draw-ings, it will be seen that our improved glass forming inachine comprises e table 2 of any .suitable character and -suoported upon end legs 3,v

`Pa=ing longitudinally through these Vend legs and supported in suitable bea-rings therein ls'the main driving shaft 4 t0 which` power muy be communicated in any suitable manner, as by un eletcric motor, beltor georing. Merely for the. purpose of illustration' we have shown the shaft 4 as provided with :i geur iwheel 5 :it one end meshing with a spo r geur wheel assumed to be connected, to the driving wheels. .The shaft `is held in position upon the legs 3 by means of. collars 7 which prevent longitudinal' movfegnent of the slnrfit.

Disposed adjacent opposite ends of "the table l and extending upward through the tuhle are the reciprocating plungeroperziting rods 8- :md 9,' und rotatably mounted upon the jice of the table- 2 and respectively concentric to the rods 8 and 9 are the mold can riers 1U and il. The carrier 11 consists vof n disk having u central opening 12 through which projects .1 hub 13 which is fixed to the trible i). and which extends Vup through the openingr 12. und which surrounds and toi-ins guide for therod 9. The table l() is annular in form, as illustrated clearly in are the coiled springs Fig. 3, this annuius` rot-ating around' eentral hub i4 which is formed with a flange lo disposed in the saine plane-as the annular table 10. This hub 14, as' illustrated clearly in Fig. 2, is fixed to the tabie in any suitable manner. Preferably both ofthe. huhs i3 and 14 are longitudinallySlotted as at 15a so that pins lfprojecting from the respective rods` Sand 9 may have sliding uitweinent in these Slots, these pins prevei'iting the rotation of these rods S and 9 with relation to the hub lt and the tai-bie.

' The periphery of the rotatable annular Carrier l0 is `furthe-( 1 with a pluralit)r of notches` 17, and opera-ting in conjunction with these notches is a pawl 1.8 which is reciprocated in a manner which will be later described, and which thus. actsto giveastep 4by step motion to the carrier. Mounted upon the xcarrier 10. are a plurality of n'iolds 19, which molds ma); be of -any suitable character' but are. iliustra-edas molds designed for the ormingof such bot tles as 'milk bottles or like. receptacies.

Mounted upon the upper end of the vertical reciprocating rod 8 .is un arm 20 and also mounted upon this rod below the arm 20 is an arm 21. Bott-ofi these arms are adjustuhle upon the rod by means of set screws orin any other suitable manner, and the arms muy be either angulariy adjusted ofertil"cally adjusted upon the rod. Passing; through the extremities of the arms and having sliding engagexnenttherein is a plunger rod. carrying an Vadjustable collar A :spring ZQf-Surifounds the rod between the I arms'gZO 'sind and bears against this cellar, and' therefore urges A'the plunger rod downward Thetiouer-e'ml of the plunger iod forn'ied as illustrated in Figlt.- This pltingeris'solid at itsQlowe'r end or head, the vhead being designated 25, and being formed with the somewhat tapered extremity 2t?.

tion with the rear 'ends of the blades and to close the blades is a. wedge or shear actuating member, designated 3l and haiing approximately the forni of a cone, the apex of which is adapted to.be inserted between the rear ends of the shear blades wl'iereby as the actuating member is raised the rear ends of the shear blades may be forced into divergent relation to each other' and the 'cuttingr edges of the shear blades brought together over the mold. Preferably the member' 30 or stud supportingthe shears has screw threaded. vertical adjustment so that the shears may be adjusted in proper position above the mold and in such position that the apex of the shear actuating. member will at all times be in position to cause a closimer of the shear. blades upon the upward moreinent'of thev actuating member. The actuating member or head 3,4 is mounted upon a pin 35 which extends downward through the plunger 15, through the table 2 and 'into position to be engaged by a tap.- pet tooth mounted upon a. cam, as will `be sov For the purliose of reciprocatinfY the plunger 23 and actuating the shearsywe mount upon the shaft 4 the cam 36."

plunger formed with a cap or closure G4, and disposal between this closure and the lower arm a coiled spring (i5 adapted to resist any upward movement of the plunger. A collar (Sb is mount-ed upon the plunger' G3 so as to limit the downward movement of the plunger relative tothe arms Gl and 62. The tubular plunger G3 is provided with a valve (37, which as illustrated, `iS a rotatable valve, so disposed that when turned in'one position it will prevent the passage of air through the. tubular plunger, and when turned in the other position vwill permit the passage of air through the'tnbnlar plunger. This valve C7 is provided with. an outwardly projecting arm 68, and connecting the outer end of this arm with the arm G2 is a linlt 69. Normally when the parts are in the position shown in Fig. l the valve (3T is closed, and this valve will remain closed so long as the plunger 63 has such position that the arm (58 is aljr'proximately parallel to the arm (32. Now upon a downward movement of the rod E) the plunger lwill be lcarried downward until the cap 64 bears against the top of one of the molds. A further d ownward movement of the rod 9 will cause a downward movement ofthe arms Gland (S2 relative to the plunger and will then cause compression ol the spring (3.5 and act to hold the cap (il in tight Contact with the mold. This further downward movement of the plunger `will cause the opening of the Valve (3T hecause of the lowering of the arm GZ relative to the valve, thus causing a downward moyeinent of the arm GS and opening the valve. lVhile the head 'Gl is incontact with the mold and the valve 'is .open air will be forced into the mold and the bottle will beV blown iti a manner readily understood by" those cognizant, with the art,

The means whereby a proper timing and rcciprocation of the rod 9 is secured is as follows: Mounted upon-the shaft -l is a cam TU, which is shown in Fig. (3. fl`his cam (0 has a circumferential cam Tl and a trans rcrsely extending cam track T2 which is of course eccentric to the axis of the shaft. The lower end of the rod 'il has a laterally projecting, pin 723 which engages in the cam Assun'iing that the rod i) is 1'aised, thenupon a rotation of the shaft l and a rotation ot the cam in the direction of thc farrow, Fig. (i. the point will enter the cam track 72 and this cam track will cause the rod 9 to be drawn downward in the manner described. "hcu the pin issues from the cam track T). it will engage the concentric portion 7l of the cam track and trai-'el therealong until it again reaches 'the entrance of the cam trackv T2. Thus there will be one actuation of the blowing plunger for each rotation of the shaft While we de not to an to limit ourselves intermitl-ently rotating the carrier 1l,- we have shown in this instance the under face of the carrier 11 as formed Awith ratchet teeth 75 withwhich a pawi or dog 76 is adapted to engage, this pawl being mounted upon a slide 77 mounted in guides 7S. The slide has a depending member 79 with which a wiper ca m 8O mounted upon the shafgt l engages. This vwipercam operates infexactly the same manner vas does the double cam 5 7 and the slide is returned to its originalposition by means of the same mechanism as heretofore de; scribed, that is, by having pivoted upon the member 79 the telescopic link 8l which'is pivoted at its lower end in the manner illus# tra'ted in Fig. 1 and which is engaged by a single-bladed cam S2 of practically the same form as the cam 5G but having `only one blade. Preferably of course the carriers 10 and ll are mount-ed upon ball bearings, but an y means for reducing friction may be used.

Inorder to prevent a rearward -movement of the carriers 1Q and l1 during the rearward movement of the actuating vpan-'ls we provide spring actuated d etents or pawls, one of which is shown in Fig. l, eaclrof these detents comprising a bracketA 83'and a pivoted latch 84:, one end of which is adapted to engage not-ches 85 formed. in`

the edge of the carrier l1 (or engage the notches formed in the edge of the carrier l0), the lower end of which. is'pre'ssedoutward by means of a -spring 86.

The operation of our mechanism willbe fully understood from what has gone before. As before stated.y the molten glassifs placed it. one of the molds on the table 2, this .mold is shift-ed bene-ath the shears and the shears a re operated to cut the glass olf the top of the mold. The mold 'then passes to the plunger and the vessel or bottle is partially formed. The transfer' boy then transfers the partially foruied vessel tothe second set of molds and upon a depression of the V.mold closure an' is forced into the interior ot thel what we desire to claim and secure by Le tters Patent. is

l. In a glass forming machine, a recipro eating rod, arms vertically and angularly adjustable on the rod. a glass forming plunger slidahly mounted in said arms for Vertical movement and disposed parallel to the reciprocating rod. a spring urging the said plunger downward an'd engaging one of said jas arms, and an adjustable stop limiting the downward movement of the plunger, said stop being engaged by the spring and normally bearing against one of said arms.

2. In a glass forming machine, a table, a tubular member fixedly mounted upon the table and extending upward therefrom, said member being longitudinally Split, a mold carrier rotatable around the tubular member and with relation thereto, a vertically movable rod disposed through the tubular member, means engaging the lower end of the rod for reciprocating it, angularly and vertically adjustable arms mounted upon said rod and spaced from each other, a plunger mounted on said arms for Vertical movement independent of the arms, a spring urging the plunger downward, a stop limiting the downward movement of the plunger, and a mold closing mounted upon the lower ciid of the plunger for free vertical movement, springs resisting the upward movement of the cap relative to the plunger, and a radially projecting member mounted upon the reeij'n'ocating rod and extending into the slot of the rtubular member.

3. In a glass forming machine, a table, a hubfniounted upon the table, a rotatable .mold carrier mounted upon the table and ro tating around said hub, a plurality of' .molds on the carrier, a fixed stud upon the hub eX- tending upward therefrom, a pair of shears fmounted upon said stud and extending over the path of movement of the molds, said shears having extensions projecting rearward beyond the pivot of the shears, a vertically reciprocatable shear actuating rod vertically osoillatable through the table and the hub and having a wedgeshaped head at its upper end adapted to be inserted between the rear ends of the shear blades to cause the closing of the shears, said. rod and head being normally depressed below the shears, a spring urging the shear blades to a divergent posi tion, and means for rotating the mold car rier to bring` a mold beneath the blades, then. actuating said rod i i :anse the closing` of the blades, and then again moving the carrier to bring another mold beneath the blades.

4, ln a glass forming mechanism, a rotatable mold carrier having ratchet teeth, a slide having movement tangential with the slide, a pawl carried by the carrier for engagement with the ratchet teeth, a member projecting from the slide, a driving shaft, a cam mounted upon the driving shaft and wiping against said member to cause a movement of the slide -in one direction, a teleseopingI link pivoted to said slide at one end, aud pivotally supported at its other end and having a tail projecting beyond the pivotal support. and a cam mounted upon the shaft and engaging said tail to thereby cause a positive retraction of the slide.

ln. a glass forming n'iechanism, a rotata ble mold carrier having ratchet teeth, a, slide having moven'lent tangentially to the carrier, a .pawl carried by the slide for engagement withl the ratchet teeth, means for intermittently shifting the slide in a direction to cause the pawls to engage with the teeth and a telescopic link operatively pivoted to said slide at one end and pivotally supported at its other end and having a tail projecting beyond the pivotal support, and means intermittently engaging said tail to therebyrause a positive retraction of the slide in a direction opposite to the direction Erst-named.
